processing latency of new airpods pro 2

I’m wondering - when one is using these for noise cancellation, transparency mode or assistive listening - how much delay there is between the original sound and when it reaches your ear. I find that too much delay interferes with locative cues about one’s surroundings and also the delay adds to a smearing of one’s own voice. Specs for these devices are thin on the ground. Does anyone have any insight?

I’m not talking about Bluetooth latency - I think that is around 120 ms - not talking about the listening feature that uses the phone microphone. Just the local device processing delay.
